Product Overview
Combining active deterrence with deep learning-based target classification, the DS-2CD2T46G2-ISU/SL is a 4MP outdoor bullet camera built for perimeter and entrance monitoring where proactive response matters as much as recording. Featuring Hikvision’s Powered-by-DarkFighter technology, the camera achieves colour imaging down to 0.003 Lux at F1.4, with 60m EXIR range extending visibility into complete darkness. Equipped with a built-in strobe light, built-in speaker and built-in microphone, it supports real-time audio warnings and two-way communication triggered by intrusion or line crossing events. AcuSense deep learning classifies targets as human or vehicle, reducing unwanted alerts caused by animals, foliage or weather. The 2.8mm fixed lens delivers a 103 degree horizontal field of view, suited to wide coverage across driveways, loading docks, car parks and commercial yard entries. With IP66 protection, an aluminium alloy body and an operating range of -30 degrees C to +60 degrees C, it is built for sustained outdoor deployment across Australian conditions.
Key Capabilities
4MP Resolution at 30fps
The DS-2CD2T46G2-ISU/SL captures 2688 x 1520 at 30fps, providing sufficient detail for identifying individuals and vehicles at perimeter entry points. H.265+ compression keeps storage and bandwidth requirements manageable without sacrificing image quality during event review.
Powered-by-DarkFighter Low-Light
With a minimum illumination of 0.003 Lux at F1.4 and a 1/2.7 inch progressive scan CMOS sensor, this camera captures usable colour detail in near-dark outdoor environments. Combined with 120dB true WDR, it handles both shadowed corners and brightly lit entrance areas in a single frame.
AcuSense Deep Learning Detection
AcuSense uses a deep learning algorithm to distinguish human and vehicle targets from other motion sources. Line crossing, intrusion, region entrance and region exiting detection are supported, allowing precise zone-based alerts that filter out irrelevant movement and focus attention on genuine security events.
Active Deterrence – Strobe, Audio Alarm and Two-Way Audio
The built-in strobe light and speaker can be triggered automatically on event detection to warn intruders before any incident escalates. A built-in microphone enables two-way audio communication, allowing operators to speak directly to individuals on site via connected software such as iVMS-4200 or Hik-Connect.
60m EXIR Night Range
Hikvision’s EXIR technology distributes infrared illumination more evenly than conventional IR, reducing hotspot overexposure at the centre of the image. With a 60m IR range at 850nm wavelength and smart supplement light adjustment, the camera maintains consistent night-time coverage across long outdoor approaches.
IP66 Weatherproof Outdoor Construction
Rated IP66 under IEC 60529-2013, the aluminium alloy body is fully protected against dust ingress and sustained water jets. The camera operates reliably from -30 degrees C to +60 degrees C, making it suitable for rooftop, wall and pole mounting in exposed outdoor locations year-round.
Best For
- Perimeter and Entrance Monitoring: The bullet housing and 2.8mm wide-angle lens provide directional coverage across driveways, gate entries, car parks and yard access points where detecting approaching people and vehicles is the primary requirement.
- Active Deterrence Applications: Sites where a camera that records is not sufficient on its own – the built-in strobe and audio alarm allow an automated or operator-triggered response when AcuSense detects a human or vehicle target inside a defined zone.
- Low-Light Commercial Environments: Powered-by-DarkFighter technology and 0.003 Lux minimum illumination make this camera well suited to poorly lit yards, unlit loading areas and outdoor stairwells where standard cameras produce degraded images.
- Installations Requiring Local Backup Storage: The built-in microSD/SDHC/SDXC slot supports up to 256GB of on-camera storage with ANR (automatic network replenishment), providing a local recording fallback if the network recorder becomes unavailable.
Why Choose the DS-2CD2T46G2-ISU/SL
Where a standard outdoor bullet camera only records, the DS-2CD2T46G2-ISU/SL adds a layer of real-time intervention. The combination of AcuSense human and vehicle classification, a built-in strobe, a built-in speaker and a built-in microphone means the camera can detect, alert and respond in a single unit – without needing separate deterrence devices or additional wiring runs. DarkFighter low-light performance at 0.003 Lux and 120dB WDR give it a meaningful edge over cameras that rely solely on IR at night, particularly in mixed-lighting outdoor environments. H.265+ compression reduces storage overhead compared to H.264 systems, and support for up to 256GB microSD provides a local recording layer that a basic IP camera without onboard storage cannot offer. Available at Security Wholesalers, the DS-2CD2T46G2-ISU/SL suits installers and end users who need active deterrence capability built into the camera body rather than added as an afterthought.
Buyer Decision Tips
Lens Coverage vs. Distance: The 2.8mm fixed lens provides a 103 degree horizontal field of view, which is well suited to covering wide areas at close to medium range – typically 5m to 15m for clear face or plate detail depending on subject size. If your installation requires narrower coverage at longer distances, such as monitoring a long straight driveway from the far end, a 4mm or 6mm variant would provide a tighter field of view and more pixel density on the subject. The supplied 2.8mm lens is best matched to gate entries, car park bays, loading dock openings and building corners where width of coverage takes priority over long-range reach.
Active Deterrence Trigger Configuration: The strobe and audio alarm on this camera are linkage actions that must be configured through iVMS-4200, Hik-Connect or the camera’s web interface. They can be set to trigger automatically on AcuSense event detection or manually activated by an operator. If the site requires 24-hour staffed monitoring with manual audio challenge capability, confirm that your VMS or NVR supports two-way audio passthrough to the camera’s built-in speaker and microphone before finalising the installation design.

Ideal Use Cases
Commercial Driveway and Gate Entry
The 2.8mm wide-angle lens covers the full width of a standard driveway or gate opening, while AcuSense line crossing detection can trigger the built-in strobe and audio alarm the moment a person or vehicle enters the zone after hours – without requiring an operator to manually initiate a response.
Car Park and Yard Perimeter
The bullet form factor allows directional mounting on walls or poles to cover specific lanes, bays or boundary lines. IP66 protection and an aluminium alloy body handle the exposure conditions of open car parks, and the 60m IR range maintains coverage across large yard spaces at night.
Warehouse Loading Dock
Loading dock environments involve frequent legitimate vehicle movement during business hours and near-zero acceptable activity outside them. AcuSense region entrance detection tied to the strobe and audio alarm provides an automated after-hours warning system without requiring additional hardware or external speakers.
Construction Site Monitoring
Construction sites often lack permanent power infrastructure, making PoE 802.3af compatibility useful for single-cable deployment. The microSD slot with up to 256GB local storage provides on-camera recording backup when network connectivity is intermittent, and the active deterrence features address the high after-hours theft risk typical of these sites.
School and Childcare Exterior Zones
The two-way audio capability allows staff or security personnel to communicate with individuals at building entries or perimeter gates without needing a separate intercom. AcuSense intrusion detection can alert monitoring staff to after-hours activity on school grounds, with the strobe providing an immediate visible deterrent response.
Choosing the Right Model
- Choose this model if: Your installation requires active deterrence built into the camera body – specifically the combination of AcuSense-triggered strobe light, audio alarm and two-way communication via built-in speaker and microphone – without adding separate deterrence devices to the installation.
- Choose a different model if: Your application requires a fixed lens tighter than 2.8mm for long-range subject identification, a motorised varifocal lens for flexible post-installation framing, or a discreet dome form factor for indoor ceiling mounting where the bullet housing would be visually intrusive.
- Choose a different model if: You need full-colour night vision without IR switching – this camera uses DarkFighter with infrared illumination rather than a dedicated white-light or colour night vision mode. Where colour identification of clothing or vehicle colour at night is critical, a camera with dedicated full-colour night vision would be more appropriate.
FAQs
- What does AcuSense actually do on this camera, and how does it reduce false alarms?
AcuSense uses a deep learning algorithm running on the camera itself to classify detected motion as either a human, a vehicle or neither. Events are only flagged and linked actions triggered – such as the strobe or audio alarm – when a human or vehicle target is confirmed. This means motion from wind-blown trees, small animals, rain or passing headlight reflections does not generate alerts, significantly reducing the number of irrelevant notifications sent to monitoring software or mobile apps.
- Does the strobe light trigger automatically, or does an operator need to activate it?
Both modes are supported. The strobe and audio alarm can be configured as automatic linkage actions tied to AcuSense detection events such as line crossing or intrusion detection, so they trigger without operator involvement. They can also be manually activated by an operator through compatible software. The specific linkage behaviour is configured in the camera’s web interface or through iVMS-4200 or Hik-Central.
- Is two-way audio confirmed on this camera model?
Yes. The interface specifications confirm 1 built-in microphone and 1 built-in speaker, which together enable real-time two-way voice communication. This allows an operator using iVMS-4200 or Hik-Connect to speak to and hear individuals in front of the camera. Note that the VMS or NVR in use must support two-way audio passthrough for this feature to function end-to-end.
- What IR range does this camera achieve at night, and how does EXIR differ from standard IR?
This camera provides up to 60m of infrared illumination at 850nm. Hikvision’s EXIR technology uses a lens-based optical design to distribute IR illumination more evenly across the field of view compared to traditional IR arrays, which tend to over-expose the centre of the image while leaving edges dimmer. Smart supplement light adjustment also modifies IR intensity based on the distance of detected subjects to avoid blown-out close-range images.
- Can this camera record locally if the network goes down?
Yes. The camera has a built-in microSD/SDHC/SDXC slot supporting up to 256GB of local on-camera storage. Automatic Network Replenishment (ANR) is also supported, which means footage recorded to the card during a network outage is automatically synchronised back to the NVR once the connection is restored. This makes local storage a genuine backup rather than just a standalone option.
- What power options does this camera support, and how much power does it draw?
The DS-2CD2T46G2-ISU/SL supports both 12VDC (via a 5.5mm coaxial power plug) and PoE via IEEE 802.3af Class 3. Maximum power consumption is 10.5W on 12VDC and 12.5W over PoE. Standard 802.3af PoE switches and injectors are compatible, with no requirement for 802.3at (PoE+) supply.
